Setting Shell Limits

for the oracle User

1、Add the following lines to the /etc/security/limits.conf file:

oracle              soft    nproc   2047

oracle              hard    nproc   16384

oracle              soft    nofile 1024

oracle              hard    nofile 65536

2、Add or edit the following line in the /etc/pam.d/login file, if it does not already exist:

session    required     pam_limits.so

3、Depending on the oracle user's default shell, make the following changes to the default shell start-up file:

For the Bourne, Bash, or Korn shell, add the following lines to the /etc/profile file (or the /etc/profile.local file on SUSE systems):

if [ $USER = "oracle" ]; then

if [ $SHELL = "/bin/ksh" ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

fi

fi

For the C shell (csh or tcsh), add the following lines to the /etc/csh.login file (or the file on SUSE systems)/etc/csh.login.local:

if ( $USER == "oracle" ) then

limit maxproc 16384

limit descriptors 65536

endif
